"I'm hugely proud of my performances, my titles, and can look back on my career with a great feeling," Vergeer said at the ABN AMRO World Tennis Tournament in Rotterdam. "Keeping going would not add anything."

• Expect a lot of nostalgia this week as San Jose, Calif., hosts the SAP Open for the last time before the tournament moves to Brazil. Here's what Peter Bodo had to say at Tennis.com about the tournament's rich history and ultimate demise:

The interesting thing to me is how completely all that history and even general public interest seems to have dried up and blown away. I mean, this was no one-off tournament that someone tried to ram down our throats. It was an organic event, with over a century of history and tradition. Can the explanation for the demise of this event be as simple as, the game "moving on"? Is the present shortfall of top U.S. players enough to doom events like San Jose?

I have problems with that theory. Granted, the U.S. still has four premium events, including one on the west coast (Indian Wells). But it’s still hard to imagine that a state as tennis-friendly as California can’t also support at least one summer tournament; it suggests some critical failure of vision somewhere along the line.
